OBJECTIVE The aim of this study was to evaluate whether intertrochanteric femur fractures can be reduced and nailed properly in the lateral decubitus position using Proximal Femoral Nail Antirotation (PFNA) as a fixation device without the use of a traction table. METHODS The study included 207 patients (81 male and 126 female; mean age: 75 years, range: 22 to 95 years). According to the Evan...

The potential for lettuce field-coring harvesting knives to cross-contaminate lettuce heads with pathogens was evaluated. Rings and blades of the harvest knives artificially contaminated with Escherichia coli O157:H7 (EHEC), were used to core three successive heads of iceberg lettuce. The coring rings and blades were inoculated by dipping into soils containing EHEC at concentration ranges of 1-...

This paper describes the structural design of a tidal turbine composite blade. The structural design is preceded by two steps: hydrodynamic design and determination of extreme loads. The hydrodynamic design provides the blade external shape, i.e. the chord and twist distributions along the blade, which result in optimal performance of the tidal turbine over its lifetime. The extreme loads, i.e....

We present a framework for generating a trivariate B-spline parametrization of turbine blades from measurement data generated by optical scanners. This new representation replaces the standard patchbased representation of industrial blade designs. In a first step, the blade surface is represented by a smoothly varying family of B-spline curves. In a second step, the blade is parametrized by a t...

In this paper we obtain a limit model for a turbine blade fixed to a 3D solid. This model is a three-dimensional linear elasticity problem in the 3D part of the piece (the rotor) and a two-dimensional problem (the nonlinear shallow shell equations) in the 2D part (the turbine blade), with junction conditions in the part of the turbine blade fixed to the rotor. To obtain this model, we perform a...

The maximum attainable head rice yield in conventional long grain milling is approximately 64%, with around 15% being lost as a result of broken kernels. primary objective this project was, therefore, to improve the yield. To achieve goal, biochemically assisted whitening processes involving application different aqueous solutions were evaluated. Head was increased for all tested liquids (3.3–3...

BACKGROUND Plastic single-use laryngoscope blades are inexpensive and carry a lower risk of infection compared with metal reusable blades, but their efficiency during rapid sequence induction remains a matter of debate. The authors therefore compared plastic and metal blades during rapid sequence induction in a prospective randomized trial. METHODS Two hundred eighty-four adult patients under...

Heat dissipation per unit volume has grown rapidly, as the size of modern electronic devices has continued to decrease. The air flow induced by an oscillating cantilever blade enhances the heat transfer performance of high heat density devices. The heat transfer improvement mainly depends on the velocity magnitude and distribution of air streams induced by the vibrating blade. Accordingly, this...

Blade imperfections are a significant explanation behind low quality and of shame for makers. Review forms done on these commercial ventures are for the most part manual and tedious. To diminish mistake on recognizing sharpened steel deformities requires more auto and precise review process. Considering this failing to offer, this examination actualizes a Blade Defect Recognizer which utilizes ...

Aiming at the non-stationary and stall flutter problems of wind turbine blade caused by transient load fluctuations, the dynamic properties of wind turbine were studied, the blade was simplify to a cantilever beam in case of the action of shear deformation and cross section rotating effect were considered in this analysis, equations of the blade were established based on D'Alemberts' principle ...
